Integra Sources vs LTTS: overview
Integra Sources
Integra Sources is a custom hardware design and software development company founded in 2014, offering electronic design, embedded firmware, kernel/driver development, and full-stack product development from a single team. Public sources disagree on exact headquarters (Astana, Kazakhstan per most directories) and current headcount (estimates range from roughly 24 to 51 employees), which is typical for a boutique of this size. The company markets itself on "turnkey product development" — hardware and software delivered by one company rather than coordinating separate vendors — and reports 250+ completed IoT and embedded projects.
LTTS
L&T Technology Services was incorporated in 2012 as a subsidiary of the Larsen & Toubro Group (with engineering heritage tracing back to 2006 as L&T Integrated Engineering Services) and went public via IPO in 2016. Headquartered in Vadodara, India, LTTS reports roughly 23,800 engineers and technologists across 22 global design centers, with embedded systems and semiconductor engineering as one of several business lines alongside automotive engineering, industrial IoT, manufacturing plant engineering, and medical engineering. The scale and public-company governance make LTTS a fit for large enterprise programs, though embedded work competes for attention against several other major practice areas.
